Questions
How big is the Acnode doorbot PCB?
It measures 55.9 × 124.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Acnode doorbot use?
21 parts, built around the PN2222A and RJ45. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Acnode doorbot KiCad files?
From the londonhackspace/acnode-cl repository on GitHub, at the commit this page was made from: the board is hardware/New-ACNode-Doorbot-Shield/acnode-doorbot.kicad_pcb and its schematic hardware/acnode-reader-direct/acnode-reader-direct.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Acnode doorbot design in my own project?
Its repository states no licence, so its author keeps all rights: ask londonhackspace before reusing the design.
